Re: (TFT) Space travel - galaxy sized dyson spheres.

[Rick Smith <rsmith@lightspeed.ca>]

Hi all,
  The Ringworld was built out of 'Skree' (if I
remember the name correctly) which is an
embarrassingly tough material.  Any culture 
that wants to build a galaxy sized dyson sphere
better have several, impossible by our standards,
tricks up their sleeves or they would likely 
conclude that doing so would be silly.

  And we can't have that!  It would spoil our
speculation!

  ;-)

  Warm regards, Rick.

But if you can get the darn thing there in the first place, then I doubt that station-keeping is going to be a tough engineering problem for someone who has solved the construction problem. Not to mention for someone who is so bored that they are doing something so inefficient as making a Dyson Sphere.
